Hi, all.
Vaadin 14 very slow rendering grid(create DOM) with lazy loading in IE11. 200 row x 35 columns.
Chrome load all page 6.5 sec.
IE11 do it 1.5 min.
Can i do something?
If I set 15 columns count, the result becomes about 15 seconds in IE.
More columns… more lags.
Are you using components inside the Grid? That will come with a performance hit for sure.
I has buttons in header row (one button → one column).
I hasn’t another components or custom renderers.
I run a perfomance debug in IE it spend all time for rendering(appendChild and other).
